JOHN H. ALDRICH, OF HOLYOKE, MASSACHUSETTS.

IMPROVEMENT IN FLIERS FOR SPINNING-MACHINES.

Specification forming part of Letters Patent No. 41,268, dated January 19, 1864.

To all whom, t may concern.-

Be it known that I, JOHN II. ALDRIOH, of Holyoke, in the county of Hampden and State of Massachusetts, have invented an Improved Flier for Slubbers and Speeders; and I do hereby declare that the following is a full, clear, and exact description of the same, reference being had to the accompanying drawings, making part of this specification, and to the letters of reference marked thereon.

Figurel is a plan of the Hier with an empty bobbin. Fig. 2 is a plan of the same with the bobbin full. Fig. 3 is a front elevation of the flier. Fig. 4 is a side elevation of the saine. Fig. 5 is a plan of the presser-arm and stop detached. Fig. 6 is an elevation of the same. Fig. 7 is a view of the pin or stem detached. Fig. 8 is a perspective view ofthe spring which connects the presser-arm with the pin and iiier. Fig. 9 is a sectional plan of the flier of D. F. Smith, patented May 3, 1859. Fig. 10 is an elevation of the same. Fig. 13 is a. detached view of Smiths arm and pin. Fig. 11 is a sectional plan, showing the presser-arm, die., as frequently applied to the best speeders. Fig. 12 is a section oi' the same at A B.

In the flier (shown in Figs. 11 and 12) the stop or cam ofthe presser-arm is made so near the end or yopening of the flier and the ears of the flier are so placed that the rovingleaves the tube abruptly to wind upon the arm of the presser, and the stop or cam a is so far from the lower ear, I, of the iiier that the leverage on the pin or stem causes them in time to work loose. In the improvement of D. F. Smith, patented May 3, 1859, Figs. 9, 10, and 13, the arm c and stem or pin D are made in one piece, and the cam or stop e put on the squared end of the stem, and a shoulder, f, is made on the stem to bear against the under side of the lower ear, g, of' the flier; but the dirt and waste is liable to gat-her around the shoulder. This cam can only be altered one or more whole revolutions of the stem, for the purpose of ad justing the force of the spring'to the required pressure on the bobbin. To obviate this difficulty, he makes two catches, q1, Fig. 13, so as to vary the strength of the spring by the equivalent of one-half a revolution; but this weakens the pin.

My invention consists in constructing a flier which admits of nicer adjustment, greater durability, and capable of a iinish which leaves fewer places for dirt and waste to gather.

To enable others skilled in the art to make and use my invention, I will proceed to describe its construction and operation.

In my flier the tubular arm t' of the flier runs a little below the cam or stop j, so as to lead the roving easily onto the presser-arm O, and leaves the parts as free as possible from anything to catch the dirt and fibers of cotton. The stop or cam j is brought close up to the bearing of the stem k in the lower ear, h, so that there is but little strain orleverage on the pin or steln, and consequently it is not liable to work loose or be bent. The spring Z is attached in the usual way, one end being hooked to the pin k between the two ears It and m, and

the other end to the flier, as will be readily` seen.

By making the cam j and presser-arm o in one piece, Figs. 5 and 6, with the squared hole a to receive the squared end of the pin k, I obtain a nicer adjustment of the pressure on the bobbin as the roving is wound upon it, for, as will be seen, Fig. 5, the pin can be separated from the presser-arm o, turned one-fourth, one-halt', or three-fourths, or one revolution, as required, to give more or less force to the spring; but in Smiths flier, Fig. 9, the cani being separate from the presser-arm c and pin D, must be turned a whole revolution to keep the relative positions of the arm and cam or stop e. If not turned a whole revolution, the cam will not allow the presser-arm to bear upon the bobbin.

I do not confine myself to the square for the end of the stem; but three, six, eight, or more sides can be substituted.

In other respects the flier is made in the usual way for firstclass speeders.

I have described the two best iers with which I am acquainted to contrast with mine. I have had my fliers tested long enough to prove their value. I know of no successful attempt having been made heretofore to obviate the above-described objections to Speeder and slubber fliers.

Having thus described the construction and operation of my invention, what I claim, and venting too great strain upon the pin and addesre to secure by Letters Patent, smitting of greater nicety of adjustment, as
